I think you need to read between the lines; or at least read the last line:
"I work 3rd shift and sit around the shop 1/3 of the time anyways, might as well get some machining done." I think what imp22b is looking for are some good arguments to present to the bean-counters to justify getting a machine to play with during the quiet of the 3rd shift. You-all are not helping coming up with reasons why it is not a good idea; whose side are you on? The Bean-Counters!!!
